To aZZ whom t may concern:

Be it known that I, FRANK CHRIsTEN, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Bellows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,form ing part ot' this specification, andin which- Figure I is a side view of my improved bellows.

-My invention relates to an improvement in bellows; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, l represents a middle horizontal board or strip, forming the division between the air-receiving chamber below and the reservoir above. has an upwardly opening valve, 2, -through which the air enters the reservoir 3 from the chamber 4. The top and bottom are of the same general construction, each having two boards, 5 6, connected by a transverse strip of leather or other suitable Ilexible material, 7. The front sections, 6, of the top and bottom boards are connected at their front ends to the nose 9 of the bellows by strips of leather, l0. This construction allows the top and bottom to assume a dat position in collapsing. The portions 6 of the top and bottom boards are jointed along their whole length upon each side to gore-shaped boards 11, the joint being made by a leather strip at'l2, and the boards 1 1 are connected in like manner by leather This board `strips 13 to boards 14 of similar gore shape, and whose opposite edges are connected by leather strips to the edge ofthe middle board,l. 55

The boards 1I and 14 are inclined inward from the outside and middle boards, so that the joints 13 move inward as the top descends or the bottom ascends, folding as shown in Fig. VII.

Between the sections 5 of the top and. bot.- tom boards, respectively, and the middle board, 1, are boards 15, 15%, 16, and 16%,which are joined together and to the boards 1 and 5 by leather strips 17, 18, and 19. The inner 65 ends of the boards 15, 15%-,16,and 1621- andthe boards 1l and 14 are connected to each other by diamondshaped'strips of leather, 20, (see Figs. I and V,) that allow the necessary movements of the inflexible boards in the expansion 7o and collapse of the bellows.

To the rear ends of the sections 5 ofthe top and bottom boards arejointed by leather strips 2l boards 22, which in turn are `jointed by leather strips 23 'to similar boards, 24, the op- 7 5 posite sides of which are secured to the end of the middle board, I, by leather joints 25..

26 27 are diamondshaped pieces of lea-ther, by which the beveled rear ends of the boards 15, 1571?, 16, and 16% are connected to the bev 8o eled ends of the boards 22 and 24.

28 is a valve placed in the section 5 ot the lower board,which permits the air to enter the chamber 4 as the lower sections, 5 6, Tall, and as these sections are raised the air passes S5 through the valve 2 into the reservoir 3, and from thence out through the opening 29 in the nose 9`and through the tuyere or nozzle 30.

Attached to the section 6 of the top board is a valve, 3l, on which bears a spring, 32, the 9c valve being covered by a perforated hood, 33, to protect the valve and prevent dust and dirt from entering the bellows.

34 is a pin secured to the center board, 1. This pin acts' to open the valve 3l when the 95 reservoir 3 is nearly closed. The object of this valve is to provide a vent for-the gases which rush back into the bellows after the air has been forced out and thus prevent danger of the bursting of the bellows, as often occurs. roo It will readily be seen that as soon as the res- Vervoir 3 is inflated again, the valve will recede from the pin, and the spring 32, bearing against the opposite side of the valve, will keep it closed until the valve touches the pin again. The bellows has central trunnions, 36,.engag ing in upright supports 37. To increase the force ofthe blast,I may placca spring, 3S, each side of the bellows, the upper end of j each spring being attached to a cross-bar, 39, at the top of the bellows, while the other ends are connected to the uprights 37 at a point below, so that the springs will tend to draw down the top.

is the operating-lever attached to a rockbar, 41.

42 are adjustable arms or strips secured to the rock-bar near its ends, and which are connected by their outer endsto a bar, 43, under the bellows by means of rods 44.

To decrease the blast ofthe bellows, I may use a spring, 45, secured at its upper end to the frame in which the bellows are supported and at its lower end to the crossbar 39. When this spring is to be used, the springs 38 would ofcourse be removed, as they are employed only when an increase of blast is desired.

I claim as my invention- 1. A bellows constructed with inclined forward top and bottom boards and horizontal rear top and bottom boards, the said boards being united, respectively,with each other by iieXible joints and suitable valves, substantially as described. y

2. In a bellows, the combination of the front top and bottom boards and the rear top and bottom boards, said boards being connected with each other respectively by ilexible joints, a rigid center board extending the entire length of the inside of the bellows, a series of gore-shaped boards interposed between the top and bottom boards and secured in place by iiexiblejoints, and the valves, substantially as described.

'as described.

3. In a bellows, the combination of center board, 1, provided with valve 2, top and bottom boards, 5 6 5 6, secured together by ilexible joints, nose 10, secured to sections 6 6 by flexible joints, nozzle on the nose, end boards, 22 24 22 24, secured to each other and to the center, top, and bottom boards,5 5, by flexible joints, forward side gore-shaped boards, 11 14 1l 14, secured to each other and to the center, top, and bottom boards by iiexible j oints,rear ward side gore-shaped boards, ,15 15'21- 16 16%` 15 15%A 16 16%, secured to each other and to the center, top, and bottom boards by flexible j oints,exible diamond-shaped pieces connecting forward boards, 11 14, and rear boards, 15 15%-, below the center boards, and the forward boards, 11 14, and rear boards, 15 15%, above the center board, and flexible diamond-shaped pieces connecting rearward boards, 16 16%, to the end boards, 22 24, substantially as shown and described, and for the purpose set forth.

4. In combination with the bellows, made substantially as described, the lever 40, rockbar 41, adj nstable arms, and rods 44, as speciied.

5. In a bellows, the combination, with the top and bottom, of a series of gore -shaped boards interposed between the same, the upl per and lower most boards having their broad ends placed in a forward position, the center boards being arranged in an opposite position, said boards and top and bottom being united by flexiblejoints, and the valves, substantially FRANK CHRISTEN.
